PETER M. KLING, OF ST. LOUIS, MISSOURI.

TRACK-BRAKE FOR STREET-RAILWAY CARS.

SPECIFICATION forming part of Letters Patent No. 404,289, dated May 28,1889. Application filed February 12, 1889. Serial No. 299,668- (No model.)

To whom it may concern.-

Be it known thatI, PETER M. KLING, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Track-Brakes for Street-Railway Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure I is a side elevation of my improved brake. Fig. II is a perspective view of the outer frame. Fig. III is a perspective view of the inner frame which carries the brakeshoe. Fig. IV is a vertical section taken on line IV IV, Fig. I. Fig. V is a detail section taken on line V V, Fig. IV.

My invention relates to certain improvements in track-brakes for railway-cars, and

is intended more particularly for use on gripcars for cable railways; and my invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the bottom of the car. To this is firmly secured a frame, 2. The shape of this frame is illustrated in Fig. II, and is composed of end posts or pieces, 3, a top piece, 4, end pieces, 5, and a cross-bar, 6. \Vithin this frame fits a movable frame, 8, composed of side pieces, 9, and a bottom piece, 10, which has a groove, 11, to receive a brake-shoe, 12. The shoe is shown in both full and dotted lines in Fig. I.

1 The sides 9 of the frame 8 have lugs 13,

which fit, as shown in Fig. I, between the inner faces of the ends 3 of the outer frame.

The frame 8 would be inserted into the outer frame before the cross-bars 6 are applied, as the latter would interfere with the insertion.

14 represents a cam pivoted at 15 to the inner frame, and 16 a cam pivoted at 17 to the outer frame. (See Figs. I and IV.) These cams bear against each other, as shown, and as the outer end of one is moved toward the outer end of the other the brake is applied to the track, the parts moving from the position shown in full lines to the position shown in dotted lines, Fig. I. The parts may thus be moved by means of links 19, (one connected to each of the cams,) secured to a crank, 20,

.on a shaft, 21, secured by a bracket, 22, to

the bottom of the car. provided with a lever, 23, (shown in dotted lines in Fig. 1,) by which it is turned to operate the crank and the links, and through them the cams.

It will thus be understood that as the crank is moved toward the position shown in dotted lines, Fig. I, the brake will be applied to the rail 24 of the track, and as the crank is moved in the other direction the brake-shoe will be raised from the track by the lower cam, 14, bearing on a pin, 30, secured in the outerframe, 2. (See Figs. I and II.) The under face of the cam is properly shaped, so that as the cam is moved from the position shown in dotted lines, Fig. I, toward the position shown in full lines the rid ing of the cam on the pin 30 will lift the frame 8, and with it the shoe.

I claim as my invention- 1. In a track-brake, the combination of a fixed frame, a movable frame carrying a brake shoe, pivoted cams, and mechanism for operating the cams to apply the brake, substantially as and for the purpose set forth.

2. In a track-brake, the combination of an outer frame, an inner frame, a shoe secured to the inner frame, acam pivoted to the outer frame, a cam pivoted to the innerframe, links connected to the cams, a crank, a shaft to which thecrank is secured, and an operating-lever, substantially as and for the purpose set forth.

3. In a track-brake, the combination of an outer frame consisting of end pieces, 3, top piece, 4, connecting-bars 6, an inner frame having a brake-shoe, 12, and lugs 13,cams 14- and 16, pivoted to the respective frames, and operating mechanism, substantially as and for the purpose set forth.

4. In a track-brake, the combination of the frames 2 and 8, cams 14 and 16, pin 30, and means for moving the cams, the frame 8 carrying a brake-shoe, substantially as and for the purpose set forth.
